Abstract: (Elsevier B.V.)

Using the tagged-photon beam of MAMI (Mainz) differential cross-sections for Compton scattering by the proton through θcms = 75° have been measured for the Δ-resonance region from 200 to 410 MeV. The data put a new constraint on the

M 1+

³² photoproduction amplitude in the resonance,

|M 1+

³²| = (39.6 ± 0.4) · 10⁻³mπ⁺⁻¹ at 320 MeV, which is (2.8 ± 0.9) % less than given by the recent analysis SM95 of the Virginia group.
